Duolingo Stopped Working on Mac Desktop OSSequoia 15.1.1

12/9/2024. I have been using Duolingo to study Spanish on my Mac Desktop for the last 2 years. All of the sudden when I click on a response, nothing happens and I am unable to click on continue. I have tried uninstalling and reinstalling Duolingo. I have gone to Duolingo.com and logged in and out, but it does not fix it. I can continue to do Duolingo on my Iphone, but not on my Mac desktop for the past week. Any suggestions? I have tried going in through Google Chrome, and Safari.
